I had never seen centipede curl up if disturbed. Milipedes do curl.
most animals get scared at one point in life. all animals will react different then some others. :)
Defense against threats and protection against disturbances are reasons why a woodlouse curls into a ball. The crustacean in question (Oniscidea suborder) curls with under-parts inward so that the harder exo-skeleton is what potential competitors and predators find.
Millipedes curl into a tight ball as a defense mechanism to protect themselves from predators. This behavior helps to shield their vulnerable underside, which is less protected than their hard exoskeleton. The curled position also helps them conserve moisture and heat.
It has to do with volume vs surface area. All things lose heat through the surface. The bigger the surface, the more heat lost. An animal curled into a ball presents the least amount of surface area for its volume, which means it takes the least amount of energy to keep warm.
they curl up in to balls if they get scared other wise they are up and sleepy.
you curl up in a ball and protect your neck, face , and vital organs. The bear will batter you a little bit, but will lose interest in a couple of minutes.
